Advice on FNA

Roughly over a week ago, I found a huge lump on my left breast and it was tender and somewhat painful when touch. Anyway, I went to see my family doctor who requested two orders (diagnostic mammogram/ultra sound, and FNA). I did mammogram/ultrasound last Thursday and turned out just a cyst which was also consistent with my last mammogram and ultrasound in prior year. That being said, my FNA appt is this Wednesday but since my ultrasound appt, the cyst appeared shrunk and no more pain or tender. Should I continue to keep my FNA appt? If it’s getting smaller, would there still be fluids to drain? I read that it can still come back later on?

I would contact the hospital for advice. They will know best

Hello Julie

Thank you for your message.

It sounds like your breast cyst has shrunk and the pain has gone which is good to hear. As @max26 says your breast team will know whether you will need a FNA or not and therefore it’s worth attending the appointment.

Cysts can appear due to normal changes in the oestrogen hormone levels. Although you can develop breast cysts at any age, they’re most common in women over 35. Sometimes they FNA the fluid to confirm that it’s a fluid-filled cyst.

It’s not possible for us to say whether there will be any fluid to drain from your cyst. Breast cysts can come back, or you may develop new cysts. The treatment for cysts is usually the same each time. You should see your GP if you think your cyst has returned or you think you have a new one.
